To store an inkjet printer, first ensure it is turned off and unplugged. Remove any paper from the input and output trays to prevent bending or curling. If storing for a short period, leave the ink cartridges installed to avoid drying out. For long-term storage, consider removing the cartridges, placing them in airtight bags, and storing them in a cool, dry place to prevent clogging or ink evaporation. Cover the printer with a dust cover or cloth to protect it from dust and debris. Store the printer in a cool, dry location away from direct sunlight or extreme temperatures, which can damage the printer's components. Avoid storing anything on top of the printer to prevent damage. Following these guidelines will help maintain the printer's condition and functionality.

Yes, the Epson WorkForce Pro WF-4740 typically includes a set of starter ink cartridges right out of the box. These starter cartridges generally have a smaller amount of ink compared to the standard or XL cartridges available for purchase separately. This approach by Epson allows customers to immediately use the printer upon setup without needing to buy ink separately. However, it’s worth noting that these initial cartridges may run out faster than the regular ones due to their limited ink supply. Once these are depleted, users have the option to buy replacement cartridges according to their printing needs - whether that be in the standard size for regular use or XL for higher volume printing. Epson designs this model to be user-friendly and ready to go, ensuring a smooth setup process for consumers.
